I IMPROVEMENT IN DROPPING-DEVICE FOR HARVESTERS.

The Schedule referred to in these Letters Patent and making part of the same.

I, OLIVER O. GREEN, of Dublin, in the county of Vayne, and State of Indiana, have invented a certain Dropping-r-Xttachment for Harvesters, of which the following is a specification.

Nature and Objects of the I mention.

My invention relates to an attachment for reapingmachines or harvesters, whereby the grain is dropped or delivered in rear of the running gear, and out of the track of the next swath or cutting; and

The first part of the invention consists in theemploymeut or use of an adjustable bearing for the supporting-arms of the swinging platform, to enable the regulation of its action, and in the provision of the platform with a cradle, to retain the grain thereon.

The second part of the invention consists in a peculiar construct-ion of automatic rest or cut-off, for the temporary support of the grain during the withdrawal of the platform.

The third part of the invention consists in the combination, with such platform, and a lever actuated thereby, of adetiector or grain-lifter, to guide the grain on to the cut-off when it is in use.

The fourth part of the invention consists in a novel devices for operating the swinging platform.

General Description with Reference to the Drawings.

platform and its accessories. Figure 4is a longitudinal section through one of a the arms that support the dumping-platform.

Figures 5 and 6 represent respectively the open and closed position of-a modified form ot'niy cut-otf.

Firmly connected by pivot-bolts a a to the under side of the beam A, which may be a part of the plat form proper, are two equal radial arms B B, one or both of whose free extremities terminate in wings I), in. the plane, of said arms and lips b, which project obliquely from said plane, for a purpose explained in the sequel.

To the upper side of said arms B B, at or near their free extremities, there is connected, by pivotbolts 0 c, a shaft,(), which occupies journal-bearings (Z ll, onthe under side of my shifling and dumpingplatform D, to whose under side are secured one or more chamfered blocks or stumps E, against which the wing 11 bears, so as to support the platform in the receiving-position, as in fig. l, and from which they are relieved, the said stumps dropping in contact with the oblique lips 12', when the plattorm is shifted to its dumping-position, as in figs. 2 and 3.

In order to enable the platform 1) to assume, when closed, either a horizontal or a depressed position, or to assume a somewhat upturned position, as in fig. 1, the chamfered stumps are made adjustable by means of slots e, and selt-screws c, or otherwise. I

The free ends ofthe radial arms may be supported on bars ff.

The afbrementioned shifting and (limping-motions of the platform are effected automatically by the provision,'on the shaft; or bolt (1, of a pinion or cog-sec- -t-or F, with which gears a rack-banG, having a blank portion G, which'permits the platform D to remain quiescent in its receiving-position during one entire half of the movement, the remaining half of the time being occupied in the operations of shifting, dumping, and returning the platform.

The rack-bar G G is connected to' a wheel, H, driven from the ground-wheel by means of a pitman, I, in such a manner as that its wheel end shall pass the dead-points, or those of least motion, at the receiving, and dumpingpositions respectively, so as to afford the grain ample time to, get on and off the platform, and so as to expedite as much as possible the passage and return of the platform to and from the dumping-position.

My cut-off or temporary rest for the grain is constructed as follows:

Attached to the beam A is a post, J, to which are secured, by pivot-bolts K K, the arms L and L,

whose free extremities are pivotedm m, to a curved head, M, from which of prongs, N. I

Pivoted to the arm L, near its point of attachment project, horizontally,- a series to the post J, is a rod, 0, whose lower end is pivoted,

o, to the long arm of a lever, l, fulcrumed, p, to the postJ, against which arm there'impinges, in the act of closing the platform, a shiping tappet, Q, which operates, through the instrmnentality of the rod 0 audarms L and L, to both elevate the cut-off and to swing backward the lower the cut ofl'. proper rela Additional pivot-holes, 1%, enable the tive adjustment of the difi'erent members of the cut-off.

In order to elevate and direct on tothe cutoff all lodged or tangled grain, I provide a lifter or deflector, the same being a plate or board, S, hinged by its front edge to the beam A, and having a wing, s, which, resting upon the short arm of the levei'l", operates to elevate the deflector simultaneously withcvery portion thereof, so as to promptly and effectually drop or deposit upon the platform the temporary accumulation of grain from depression of the cut-off, the said deflector dropping flatly upon the beam A on the closing of the platform 1).

A cradle, T, upon the top of the plattorm 1), serves to gather to the middle of the said platform the grain falling upon the same.

A spring, V, entering a recess, W, in the coggcd sector, serves to hold the latter in place, so as to prevent any zu-cidcmtal movement of the same.

The platform 1) has attached to it a. hook,U, which,

entering the re-entrant-angle or throat of the divider (not shown) may, on the opening of the plat lorm, operate to drag out trom, and clear the said throat of and prevent the accun'iulation of grain and trash.

\Yhenever it is desired to employ a more open form of cut-oft" than the one represented in figs. l and 2, it may e constructed as shown in figs. 5 and 6, the rod L in this case being pivoted at one end to the upper portion of the curved head M, while the other end of said rod is pivoted to-thepost J, at or near the mid-length of the same.

Operation. The machine being advanced so as to cut the grain, the latter, in falling from the reel, .(not shown,) drops upon the platform 1), and is by it shifted laterally to a. .position behind the main frame, and is there dumped without disturbing or changing the direction of the grain. I

The instant the platform 1)- leaves its closed position, the. cnt-otf drops into its rcceiving-position, and the ll( l'l('lfl't)l' becomes elevated to a position which enables it to tbrwurdahe grain to the cut-off.

The platform l) having delivcredits load of grain upon that portion of the. ground outside of the track of the cutter, returns to its closed position, and simultaneously tlu-rewith-the cut-off and the deflectt r return to their respective non-elicctivepositions, when the work proceeds as before.

While describing the essential features of my invention, l reserve the right to modify the same as circumstances may require; for example, the described mechanism may be capable, by uncoupling, of being changed at will from an automatic to an optiona movcn'lent under control of the driver, through the medium of a suitable uncoupling-device, and hand or foot-lever, or treadle.

The prongs of the cut-off may, for some descriptions of grain, be covered with sheeting or canvas.

The arm L of the cut-off may be prolonged in front of the post J ,-and be comiected with the short instead of the long arm of the lever l, by a cord or wire.

The wings I) and lips b may operate directly against the under side of the platform.

The lever P may be operated from the'cogged sector F, instead of from the platform D.

The wing 12 and lip I) may be on either one or both of the arms B B.

Claims.

I claim, as my invention 1. The adjustable ehamfered stumps or projections E,- for the purpose designated.

2. The'combination and arrangement of the arms L L, head M, prongs N, rod 0, and lever 1, constituting an automatic cut-otf, as and for the purpose described.

3. The combination, with a side-delivering platform anda cut-elf, constructed and operating as herein set forth, of the tappet Q and lever P, for operating the I 'Witnesses:
